This invention relates to improvements in the dass 0f horse hay-rakes,and'the same consists of certain nove1 features in-the peculiarconstruction, eombination and arrangement of the diffierent parts asWill be hu16illafter set forih in del1ail.

In the drawings-Figure 1 is a brokenaway p1an; one ot' the wheels beingremoved, Fig. 2, a broken-away transverse seetion 011 1ine 2, Fig. 1,looking in the direction indicated by the arrow; Fig'. 3, a brok'en-awaytransverse section on 1ine 3, Fig. l; Fig. 4, a transverse section 0111ine 4, Fig. 3; Fig. 5, a broken'-away view in perspective of a majorpart 0f the deviee; Fig. 6, a broken-away transverse section on 1ine 6,Fig. 1; Fig. 7, a

broken-away transverse seotion 011 line 7, Fig. 1; Fig. 8, a plan 0f adetached detail; and Fig. 9, a transverse section 0n 1ine 9, Fig. 1.

A represents the axle, A A the usnal sulky wheels mounted on therespeetive ends there- 0f, A the rake-head, A A bearing-boxes supportingthe rake-head in proper position with reference so the axle, and A thecurved springrake teeth which are secured t0 the rake-head in any.suitable mauner.

The draft-frame consi'sts 0f the shaf manibers B B, mounted 011 the axleand eonnected by cross-bar B and foot-rest; B. Tha front ends 0f bracesO O are attached 130 the respective shafts; the rear ends having loosemally in engagement With the ratchet-wheels by a spring a This providesfor the rotation of the whee1s and axle together 011 the fotwardmovement; the ax1e rernaining stationa1y when backing the rake.

The means employed for dmping the rake will next be described. Aratchet-disk 10 (Figs. 1 and is rigidly mounted. on the axle at a poinbbetween the shafts. Adjacent t0 this disk is a tooth-segment; 11,100se1ymounted 0n the ax1e, and. adapted to be thrown into and 01111 ofengagement with'the ratchetdisk, thus forming a c1utch arrangement. Thelower end 0f the arm 12 is loosely mounted 0n the axle; the upper endextending up bebween the bars of the rake-head, and the shoulders 13bearing agains t the under side thereof. The arm 12 is conncted with thernoving cluteh member 11, by two bars 14. A eam-shaped plate 15 isloeated about midway between oho moving clutch member and arm 12, and isretained in place by the connectingbars 14; these parts together forminga sding carriage. The lower end 0f a lo cking angle-bar 16 (Figs. 1, 5and 6) is inserted in one 0f the shafts; the upper unattaehed endterminating adjacent to, and just out of eont-act With, cam-plate 15,when the parts are in the normal position shown in Figs. 1, 5 and 6.

The dotted lines in Fig. 6 indicate the opposite position of theea.rriage and can;-p1ate; the ra'ke haVing just diseharged its load.When the eluteh mechanism is thrown into engagement, the position 0fangle-bar 16 will be 0n the opposite side 0f cam-plate 15 from thatshown in Fig. 1. NOW as the rake-head rotates, in the actof dumping thedetached end of bar 16 bears against that side of 'nhe eam-plate andholds the clutch-gear into engagement until the rake has reached itslimit 0t' movement, when the edge 0f cam-plate will have eleared thelocking-end of bar 16 (dotted. 1ines Fig. 6) and ehe clutch-carriage maybe returned 130 its normal position'. One end of stationary rod 17 isrigidly fastened to the inner end b of brace C, and the opposite end tothe eorre'zsponding end 0f shaft B, as shown in Figs.1and 5. A groovedcollar 18 is loosely mounted on rod 17 so as to have a sliding movementthereon'. An angle-r0d 19 has 0110 end. loose1y looped aroundrod 17, asat 20. The opposite enc1 of rqd 19 is bifurcated and straddles the edgeof arm 12, as

shown at 21, Figs. 1 and 5. A spiral spring 22 is eoilecl on stationaryrocl 17. One encl of tl1is spring is secured to slicling eollar 18, asat 23, ancl the opposite encl1oopecl around tl1e onter end of rocl 19,as sl1own at 24. One end of arm 25 is attaol1ed to :r0cl 17, while theopposite forked end 26 embraces rocl 19 and assists in snpporting saicl10(1 in its proper position. A oam-pieoe 27 is rigidly mountecl onstationary rod 17. The cam-snrfaee 0r faee is in the aro of a clroleWith referenee t0 the axle. A rod 28 is loosely supported fron1 therakel1ead (Fig. 5) by loops 29. The bifnrcated encl 30 0f rocl 28stradclles tl1e grooved sliding collar 185 the opposite encl being bentdownwarclly and insertecl in the diagonal groove 31 (Fig. 8) instationary cam-pieee 27. The inner end of a lever 32 is loopecl arounclrod 19; tl1e opposite 0r onter end resting loosely on the lowerhorizontal part 33 of a shifting Standard 84, Figs. 5 ancl 9. Aheelplate 35 is mounted 011 tl1e npper end of standarcl 34,whioh passesclown tl1rou gl1 sleeve 36, for1ning a part of eross-bar 37 seourecl totl1e frame. A spring 38 supports the standard and returns tl1eheel-plate ancl its standard to a normal position when the pressnrethereon is relaxed. The lower part of standarcl 34 is tnrned atright-angles, as shown in Fig. 9, ancl tl1en bent over anrl baekwarcl topresent ehe inelined surface 39, and a shoulder-stop 40, against whiehbears the outer encl of lever 32 when the rake-parts are in their normalposition. Tl1e respective encls of lever 32 are aclaptecl to have alateral 1novement in a horizontal plane, by reason 0f being snpported onthe end of a projecting arm 41 as the elnteh is thrown into anrl out ofengagement. The pressure 01: spring 22 is 110rmally toward the clutcl1mechanism for rotating tl1e rake-heacl, so tl1at when the operatorforces (10W11 standarcl 34 far enongl1 for the onter end of lever 32 t0pass over shoulder 40 and rest upon the inelined snrfaee 39, whiehehange of position is bronght about by the pressure spring 22 throwingtl1e olutel1 into engagement through tl1e medinn1 of rod 19, an(loausing the rake-l1ead to rotate in dun1ping its load. During thisoperation spring 22 is eo1npressecl by oan1-piece 27, rod 28, andsliding collar 18, loosely mounted on stationary rod 17, as the diagonalgroove in cam-pieee forees rocl 28 ancl eollar 18 against the spring,whiel1, when it has acou1nulated 'suffioient power, forces rod 19 in theopposite direetion and disengages tl1e elutolrmeehanism and stops tl1erotation 0f the rake-lieacl. \Vhen the olutoh is clisengaged, the onterencl 0f lever 32 moves up the inolined surfaoe and drops into its normalposition back of the shoulder formed 011 the lower end of the standard.An arm 42 is loosely monnted 011 the axle (Figs. 1 and adjaeent 130 tl1e011te1 side of tl1e olutoh-disk. Tl1e npp'er encl of this arm isseenredto the rake-head so as to rotate therewith; the dotte"d lines inFig. 3 indicating its opposite 01 horizontal osition. T0 t-l1is arm isloosely attaehed one encl of 10d 43, the opposite bifnrcated end (Figs.1 and 4) being eonnected Eo tl1e lower encls 01": links 44 and 45 by aholt 46.

Tl1e upper ends of these links are loosely atelinecl snrfaee 51 and astop-shoulcler 52, be'

ing a duplieate of companion standard 34. New, as tl1e rake-head isrotated in tl1e act of dumping, the holt 45, conneetingmod 43, and links44 ancl 45 ricle up tl1e inelined surfaoe 51 of the lower part ofstandarcl 47 and drop in behincl shonlder 52, as indieated by dolr tecllines in Fig. 3, thus locking and holding the rake in its higl1estposition after the rotating cl11toh-mechanism has been thrown 011t ofengagement. By pressing down on heelplate 49, this loeking mebhanism isclisengagecl and the rake drops. By this arrange- 1nent the rake isalways nnder tl1e eomplete control of:' the operator.

Having thus described my invention, what I claim as new, ancl desire tosecure by Letters Patent, is-

1. In a hay-rake, the oombination with tl1e axle, of a ratohetdisk,rigidly mounted thereon, a toothed segment, loosely monntecl 011 saidaxle, an arm 12, loosely mountecl 011 saicl axle, the upper enrl looselyengaging with the rake-l1ead, the bars 14, oonneeting tl1e movablecluteh-mennber and arm 12, the stationary rod 17, tl1e grooved eollar18, loosely monnted thereon, the rocl 19, having one Gl1fl looselyloopecl arouncl rod 17; the opposite bifureatecl end engaging with arm12, the spiral-spring 22, coiled on rod 17, the ean1 27, and 1 0(1 28,substantially as and for the pnrpose set forth.

2. In a hay-rake, tl1e oombination 0f the axle, tl1e oluteh segment, arm12, the samplate, loeated therebetween ancl moving with the rake-head,the locking angle-bar 16, and tl1e spring, adapted to impart a slidingmovement to tl1e eam plate, substantially as and for the pnrpose sei;forth.

3. In a hay-rake, tl1e combination with the stationary rocl 17, of aoam-pieee, provicled on it s face with a diagonal groove and rigidlymounted on said rod, the rake-head, the sliding-oollar 18, thesliding-rocl 28, loosely supported fro1n tl1e rake-head. ancl having oneend inserted in saicl diagonal groove,the opposite end engaging witheollar 18, tl1e spiral-spring 22, the rod 19, the ratohet-disk, rigidlyn1onnted 011 tl1e axle, a toothed seg- 1nent, loosely monnted on Eheaxle, and the lever connection for throwing the olutch meehanism into anengagecl position,substam tially as set forth.
